Find your gut triggers.
In days, not years.
Talk, type, or snap. GutSync turns one sentence into a structured timeline, finds what's setting you off, and builds the case that proves it.

The problem
The problem isn't you. It's the diary.
Gut conditions are everywhere, diagnoses run years late, and half of all food diaries die inside two weeks. The tool quits before the pattern shows up. GutSync was built to outlast week two.
Americans live with a chronic digestive disease, one of the most common reasons to end up in a doctor's office.
colorectal cancer in adults under 50 has been climbing since the mid-1990s. Nobody is sure why yet.
of people with IBS-level symptoms have never been formally diagnosed. They cope alone.
the gap
abandon dietary self-monitoring within the first two weeks. Manual logging asks too much, every day. So the diary that should help you stops getting written.
GutSync is the diary that closes the gap, and keeps getting filled in. Built for the people whose food is their medicine.
How it works · 01
Log it in one sentence. Or one photo.
Say what you ate, snap your plate, or note a symptom in plain language. GutSync parses it into a typed, timestamped, Bristol-aware timeline. No forms. No dropdowns. No app to remember.
It actually reads your timeline.
Ask it anything. It answers from your real entries, in plain language.
No app to open. Text the bot.
The hardest part of any food diary is remembering to open it, so GutSync skips the app entirely. Connect Telegram and message the bot the way you’d text a friend. It files the meal, symptom, or note for you, even when GutSync is closed.

How it works · 02
It doesn't guess your triggers. It measures them.
Every food gets measured against your own baseline: how much it raises symptom risk, how many hours later, and whether the pattern survives correction for coincidence. Triggers land as strong, likely, or possible. “Dairy raises bloating risk 2.1x, 8 to 12 hours later” is an answer you can act on.
Patterns spreadsheets can't see, with the statistical weight to back them. And when one keeps showing up, it becomes a suspect.
How it works · 03
Open a case. It stays open until the answer is earned.
Name a suspect and GutSync opens a standing n-of-1 trial on it. The case feeds on the logging you already do, keeps honest score, and closes the way tracking never does: with a verdict.
Name your suspect
A food, an ingredient, a habit. One tap and GutSync drafts the trial: what to cut, for how long, what counts as evidence.
It runs itself
No study forms, no check-ins. The case reads the entries you were already making and keeps the score honest.
The verdict lands
Confirmed means you finally know. Cleared means a food you feared comes back to the table.
Two ways to run one
Challenge protocol
A guided elimination diet with a real reintroduction. The strongest evidence on the fastest clock.
Observational
Full autopilot. Keep logging like normal and the case scores every new day in the background.
The AI drafts the protocol and narrates the case. But every verdict is issued by the numbers, against thresholds fixed before the case opened. You'll never get one the evidence didn't earn.
How it works · 04
Generic on Day 7. Specific on Day 60.
The longer GutSync sits with your data, the less you have to spell out. Stress, travel, a course of antibiotics: it all shapes the read. Ask the same question in week one and week nine and watch the answer get personal.
Six layers of context. One sharper answer.
What you've told it, what it's noticed, and the situation you're in right now. Every entry lands inside that picture, so you don't repeat yourself.
The "right now" layer of memory.
Tell GutSync what's happening (travel, a protocol, a hard week) and it overlays the stretch on your timeline, so it stops blaming your trigger list for explainable flares.
Time-bounded overlays with start and end dates. Entries logged inside a context get explained by it, so a flare during your trip doesn't rewrite your baseline triggers.
Same question. Sharper answer.
Memory, life context, and 60 days of data turn a generic reply into yours.
Asking on
Day 7
Bring it to your GI
One tap. A diary your GI actually wants.
“I think it was something I ate” isn't a plan. Export a chronological, Bristol-aware record with trigger correlations and life context overlaid. Your specialist opens it and reads it like a chart.
Skip the notebook. Walk in with data.
The export is a real document: Bristol-scale aware, context-annotated, and all record — your entries and the numbers behind them, never a transcript of AI chatter.
Every entry, in order, with timestamps. The format your specialist actually reads.
Color, consistency, urgency, and notes. The GI-clinician vocabulary, captured verbatim.
Travel, illness, diet, stress. All annotated alongside symptoms so a flare doesn't read as a baseline.
The patterns that earned their statistical weight, ranked by how hard they hit.
Why not just use…
Built differently from every other gut diary.
Other apps hand you forms to fill and charts to decode, then call it insight. GutSync handles the entry, the structure, and the pattern hunt, then hands you answers.

Why they stayed
From the people whose food is the variable.
Why GutSync exists.
One bad infection, two years of guessing. The story behind the product.
In 2024, a Campylobacter infection wrecked my gut for almost a year. My doctor told me to keep a food diary, but I found the act of logging too high-friction, so I started passing my data into LLMs to find patterns.
I built GutSync to eliminate that friction while providing deep insights into your patterns and gut health on autopilot in a way that other apps and LLMs alone currently can’t.
I believe that effortlessly tracking health data, combined with an AI that proactively monitors your goals and patterns alongside real statistics, will become a major part of the future of health and longevity.
